Determination Of The Substrate Specificity Of Citrus Paradisi Flavonol Specific 3-O-Glucosyltransferase Mutant D344p, Nathan R. Spaulding

Undergraduate Honors Theses

Plants produce a vast array of secondary metabolites. A group of phenolic compounds, the flavonoids, are metabolites ubiquitous among plants and are known to aid in processes such as plant reproduction, UV defense, pigmentation and development. In relation to human health, flavonoids have been found to possess anti-inflammatory, anti-cancer, and antioxidant properties. Flavonoid’s ability to participate in so many interactions is due in part to their subclass variation and further chemical modification. One such modification is glucosylation, where a glucose molecule is added to the flavonoid substrate. The enzymes that catalyze these reactions are known as glucosyltransferases (GT). Citrus paradisi …
